Kinematics #4

In the game of football everyone has a position either on offense or defense. If its from playing offensive line or receiver or quarterback, everyone has a job that their responsible for. During a typical football game players run on and off the field. Their total displacement from getting off the bus to getting back on is zero. When on the field players also show other signs of kinematics. For example, as an offensive lineman when we break from the huddle we run to the line and get down in our stance. Since we are at rest our velocity at this point is zero. But when the ball is snapped in a matter of seconds our velocity and acceleration increases until contact with a defensive player. When making contact our velocity and acceleration decrease but never hit zero. Once again physics has been proven to be actively involved in football.
